Referring to the drawings in detail the device embodies a hollow box-like body comprising a lower wall 1 an upper wall side walls 3 and 4. and front and end walls 6 and T The upper wall is provided with two doors and 9 to permit access to the interior of the body member, and the rear wall 7 is also provided with a door 10 for a similar purpose. The side walls are preferably strengthened by longitudinally-extending members 11, 12 and 13. Extending transverselv through the body of the device 0 erm ns learner TREET-SWEIEJIP'TER. Q:

Although only one counterweight is shown it is obvious that there may be one on each -of of the device.

Extending between the side walls 3 and i above and slightly in the rear of the shaft 19 is a r voluble shaft 28 bearing-between'thewalls? and 'l a fan .29 and on the outside '95 of the wall 3 a pulley 30 which ieceives abelt 22' extending from the anniilar flange 17 for the purpose of rotating the fan when the device is movedp The function of the fan is to supplement the action of the brush .in driving .the dirt and dust-laden air rearwardly over the inclined partition Extending between the walls 3 and 4 near the upper rear portion of the device is a vertical partition 31 and between the, lower edge of the partition 31 and the rear wall 7 is a horizontal partition 32 of a foraminous and reticulated material to constitute a screen, Extending along the upper. inner faces of'the walls 3 and e are a pair of air passages 33 and 34.
